We analyze the association between cohesive subgraph visualization (CSV) plot and k-clique community detection. Then, we propose an algorithm named LargeKCliqueCSV to detect large k-clique communities, which reduces search space through CSV plot. At last, we conduct experiments on Stock Market ...
文献《1》中提到,一般网络的Q值在0.3 ~ 0.7之间,能够说明很好的community structure。 回过头来看看Modularity的计算方式,会发现它对于community的衡量比早期的一些标准(例如k-clique)要简单很多。它并没有要求community内部具有某种结构,也不要求community中的每个node达到某种标准,而只统计community中内部和外部的边的总数。
K-Clique Communities acliqueis a subset of vertices of an undirected graph such that its induced subgraph is complete; that is, every two distinct vertices in the clique are adjacent. Ak-clique communityis the union of all cliques of size k that can be reached through adjacent (sharing k-...
As k is increased, the k-clique communities shrink, but on the other hand become more cohesive since their member nodes have to be part of at least one k-clique. Weighted Network Analysis(WNA): It is an extension of the unweighted modularity. For weighted Networks, see“Weighted Network in...
communities, and the remaining connections are made to randomly chosen members of the same community. Whenzoutis a half-integer\(k+\frac{1}{2}\), half of the vertices havekinter-community connections and the other half havek+ 1 inter-community connections. The GN benchmark produces graphs ...

回过头来看看Modularity的计算方式,会发现它对于community的衡量比早期的一些标准(例如k-clique)要简单很多。它并没有要求community内部具有某种结构,也不要求community中的每个node达到某种标准,而只统计community中内部和外部的边的总数。从计算上,这是很容易做到的,所以后来基于Modularity的算法,在复杂度上都比早期的算法...
